Here, we present the first radial velocity curve for this system. It is found, that HD 553 is a double-lined spectroscopic binary. Despite the large luminosity difference, the two components of this system are of very similar mass. The primary, a K0-giant, fills a large fraction of its Roche-lobe. The secondary is, despite its very similar mass, still a late-type dwarf. The radial velocity curve allows to constrain several stellar and system parameters.
